In this paper we present an airspace capacity research project at NASA’s Ames and Langley Research Centers within the Terminal Area Productivity program, TAP. We describe an application area that deals with arrival traffic management and control in a 2010 time frame. We investigate utilizing and integrating air traffic control and aircraft automation. We address potential benefits and limitatio...

Airport delays are a significant problem in the United States air transportation system. Between 1999 and 2000 the number of flights delayed increased by 20 percent despite only a 0.4% increase in total operations. Newark International Airport (EWR), one of New York City's primary airports, is one of the airports in the United States most impacted by delays. Newark had the highest percentage of...

This project is concerned with the development and evaluation of an integrated approach to sound-based access to spreadsheets. The primary target user population is visually impaired users, employing speech-based screen readers as their main means of accessing the data. Other users may benefit from the approach in situations where sound may provide an effective alternative or complementary mean...

Development experience of ore traffic and extraction simulation system in underground part of potash mines is reviewed. Distinctive features of suggested simulation model (combine complex extraction, using conveyor transport and transfer point in continuous ore traffic simulation) are represented. Implementation features of bundled software ”Рудопоток” are considered.

UNLABELLED The purpose of this study was to investigate the possibility to integrate a free head motion eye-tracking system as input device in air traffic control (ATC) activity. Sixteen participants used an eye tracker to select targets displayed on a screen as quickly and accurately as possible. We assessed the impact of the presence of visual feedback about gaze position and the method of ta...

The reductions in task load resulting from the increasing automation of air traffic control may actually increase the requirement for controllers to maintain high levels of sustained attention in order to detect infrequent system malfunctions. A previous study indicated that individuals scoring high on a distractibility scale found it difficult to maintain sustained attention on a monotonous, b...

To assess operational performance of air traffic control sector, a multivariate detection index system consisting of 5 variables and 17 indicators is presented, which includes operational trafficability, operational complexity, operational safety, operational efficiency, and air traffic controller workload. An improved comprehensive evaluation method, is designed for the assessment by optimizin...

There is disagreement among researchers about the distinction between dynamic and static spatial performance. Given that dynamic spatial performance is supposed to be important for some occupations, such as air traffic control (ATC), it is germane to have evidence about the likelihood of that distinction. In the present study, a battery of printed static spatial and reasoning tests were applied...

This study examines the nature of adolescent attachment to parents and peers during adolescence. A projective measure was used to classify 99 11th and 12th grade students into secure, insecure dismissing, and insecure preoccupied attachment groups. Respondents identified their primary attachment figure by nomination and by rating the level of attachment support they received from mothers, fathe...

Traditionally, models used in air traffic control and flow management are based on simulating the trajectories of individual aircraft. This approach results in models with a large number of states, which are intrinsically susceptible to errors and difficult for designing and implementing optimal strategies for traffic flow management. This paper outlines an innovative approach for the developme...
